## What it is
Marble Marcher is a video game demo built on a fractal physics engine with fully procedural rendering, where players roll a marble across ray-marched fractal surfaces to reach a flag across 24 levels. It is written in C++ using Eigen and SFML, and is no longer under active development in this repository.

## Use cases
- play a physics game with procedurally rendered fractal levels
- study a real-time raymarching fractal renderer
- explore fractal physics engine implementation in C++
- speedrun 24 unique fractal marble levels
- learn how to combine SFML with GPU shader-based rendering

## When to choose
- you want a unique fractal-based physics game experience
- you need a reference implementation of real-time raymarched rendering
- you want to contribute to the community edition fork

## When to avoid
- you need actively maintained software
- you want a general-purpose game engine
- you need cross-platform mobile or web support

## Facets
- artifact type: application
- maturity: maintenance
- function: game-engine, graphics, simulation
- domain: graphics, simulation
- platform: windows, cpp, cross-platform
- tags: fractal-physics, procedural-rendering, raymarching, video-game, opengl, game-development, linux, macos
